High power LED lens filling encapsulation silica gel
A, product features:
1, this product divides the A and B component packaging, all be colorless transparent liquid, avoid light environment can save time.
2, silicon - oxygen (Si - O) key chain structure of mainly, so not easily by ultraviolet and ozone by decomposition, no p-bond exist, at high temperatures (or radiation) molecular bond doesn' t break, can be in 50 ° C ~ 200. ° C van turn in use for a long time. After seven days of intensifying test ° C 300 changes after, not cracked, no hardening, colloid from external craze after can automatically healing.
3, colloid after curing shows colorless cellophane tape thallose, PPA and metal has certain adhesion and sealing is good.
4, excellent electrical insulating performance and good sealing.
5, suitable for filling production high power LED lens.
Second, recommended process: different encapsulating techniques, the proposal with different ratio, get better effect.
1, by weight, than for A: B = 1:1 ratio with glue, mix 8 minutes.
2, vacuum TuoPao 10 minutes.
3, in the glue before, please stents and lenses in 130 ° C next preheating 60 minutes above except tide.
4, first 80 ° C roast 1 hours again warming to 120 ° C roast 2 hours, segmentation curing can effectively solve the bubble to enhance yield.
Three, the matters needing attention
Production should be calculated with the amount of plastic, must be in operation time to glue finished with glue. Stir evenly when must, otherwise, it will affect curing incomplete product performance. This product is the silastic products, use should be paid attention to during the avoid with a material contact:
Organic tin compounds and other organic metal compounds;
Contain organic tin compounds silicone rubber,
Sulfur, more sulfur compounds, poly (PSF and other sulfur-containing materials;
Amines, ethyl carbamate fat or other containing amine materials,
Unsaturated hydrocarbons plasticizer,
